Description

Fixture for holding a substrate

This creation is related to a fixture, especially a fixture for holding a substrate.

As electronic products become lighter, thinner, smaller, and more versatile, they also drive the development of semiconductor chip packaging technology, which in turn drives the chip package to be multi-legged, thinner, and pin-thinned, even without Foot construction and other technologies.

In order to cope with the trend of thinness and shortness, the total thickness of the substrate for manufacturing the circuit board or the package substrate is less than 0.1 millimeters (mm). The rigidity of the thin substrate is far less than that of the conventional substrate, so it is easy in the process because The spray of the chemical liquid causes problems such as the bending of the substrate, which in turn causes the substrate to be stuck by the process equipment, and must be scrapped, so as to increase the overall manufacturing cost.

As shown in FIG. 1A, when the substrate 10 is moved toward the nozzle rod 12 by the roller 11, the one end of the substrate 10 is bent and deformed, and the roller 11 and the nozzle bar 12 (or other transmission members) are wound. Between the two, the board problem is caused, in addition to the damage of the substrate 10, the production line is stopped and the production capacity is reduced, and in serious cases, the process equipment may be damaged.

In addition, as shown in FIG. 1B, since the substrate 10 is driven by the frictional force between the roller 11 and the surface of the substrate 10, that is, the substrate 10 is in direct contact with the roller 11, the surface of the substrate 10 is easily excessively rubbed. Scratches, depressions, or foreign matter sticking from the roller 11 are formed, thereby causing a loss in yield of the substrate 10.

Therefore, how to overcome the problem that the deformation of the substrate in the above-mentioned prior art and the surface of the substrate are directly affected by the roller has become a problem to be solved at present.

In view of the above-mentioned various deficiencies of the prior art, the present invention discloses a jig for holding a substrate, comprising: a first frame having a surface on which a plurality of first magnetic members are protruded; and a second frame; A surface is provided with a plurality of second magnetic members protruding and corresponding to the first magnetic member, the first magnetic members being attracted to each other by the magnetic force by the magnetic force.

In the jig of the present invention, the first frame and the second frame respectively have at least one first protrusion and at least one second protrusion protruding outward in the non-thickness direction, and the first protrusion and the first protrusion The positions of the two protrusions are staggered from each other, and the frame faces of the first frame and the second frame are rounded.

According to the above-mentioned jig for holding the substrate, the surface of the first frame and the second frame respectively have a plurality of first recesses and a plurality of second recesses for respectively fitting the first magnetic members and the second The magnetic component, the first magnetic component and the second magnetic component are made of a magnet, and the first magnetic component and the second magnetic component are cylindrical in shape.

In the jig, the surface of the first magnetic member and the second magnetic member has a protective layer, and the protective layer is made of Teflon.

In the embodiment of the present invention, the material of the first frame and the second frame is a polymer material, and the substrate is a circuit board or a package substrate.

It can be seen from the above that the present invention magnetically holds the substrate between a pair of rigid frame jigs and then carries them by rollers. At this time, the jig provides a large rigidity of the substrate, and can avoid the conventional thin substrate. Curl, deformation and warpage between the transmission mechanism of the production equipment (for example, rollers or conveyor belts, etc.), thereby preventing the problem of the card. In addition, the fixture of the present invention is located on the outer side of the substrate, so that the substrate can be protected from direct contact with the transmission mechanism (for example, a roller or a conveyor belt, etc.), thereby avoiding scratches on the surface of the substrate, foreign matter adhering, and residual chemicals. Problems such as liquid cross-contamination to increase the yield of the substrate and reduce the overall cost.

The embodiments of the present invention are described below by way of specific embodiments, and those skilled in the art can readily appreciate other advantages and functions of the present invention from the disclosure of the present disclosure.

It is to be understood that the structure, the proportions, the size and the like of the drawings are only used in conjunction with the disclosure of the specification for the understanding and reading of those skilled in the art, and are not intended to limit the implementation of the present invention. The conditions are limited, so it is not technically meaningful.

In the meantime, the terms "outside", "missing" and "one" as used in this specification are for convenience of description only, and are not intended to limit the scope of the creation of the creation, or the relative relationship may be changed or Adjustments, if there is no material change in the content of the technology, are also considered to be the scope of implementation of this creation.

The figure shown in Fig. 2 is a three-dimensional exploded view of the jig for clamping the substrate. As shown in FIG. 2, the fixture includes: a first frame 21a having a surface on which a plurality of first magnetic members 22a are protruded; and a second frame 21b having a surface provided with a protrusion and corresponding The plurality of second magnetic members 22b of the first magnetic member 22a are attracted to each other by the magnetic force and the second magnetic members 22b.

In this embodiment, the surface of the first frame 21a and the second frame 21b respectively have a plurality of first recesses 210a and a plurality of second recesses 210b for respectively fitting the first magnetic members 22a and the second magnetic force. The second magnetic member 22a and the second magnetic member 22b are, for example, cylindrical magnets, and the number and magnetic force of the first magnetic member 22a and the second magnetic member 22b can be made according to actual conditions. Different adjustments.

The frame faces of the first frame 21a and the second frame 21b are rounded, but the first frame 21a and the second frame 21b respectively have at least one first protrusion 211a and at least one second. The protrusion 211b, the at least one first protrusion 211a and the at least one second protrusion 211b protrude outward in a non-thickness direction of the first frame 21a and the second frame 21b, and the first protrusion 211a and the second protrusion The positions of the protrusions 211b are shifted from each other, so that the automation device can join and separate the first frame 21a and the second frame 21b by the first protrusion 211a and the second protrusion 211b.
